6000psi Fisher Controls Propane Regulator 1301F High Accuracy For Compression

Fisher 1301F-2 Model Brass Body Material High Pressure Gas Regulator

Types 1301F and 1301G regulators are self-operated, high-pressure regulators, which can

be used where high pressure gas must be reduced for use as pilot supply pressure in pilot-operated

regulators or as loading pressure in pressure-loaded regulators. Types 1301F and 1301G regulators

can also be used in many other applications as high-pressure reducing regulators for various gases.

The proven reliability and accurate regulation of the Type 1301F high pressure regulator makes it ideal

for numerous high-pressure drop applications. This multi-purpose regulator can be used as pilot supply

or pressure-loading regulators where high-pressure operating medium must be reduced for use by gas

regulator pilots or pressure-loaded regulators. Its rugged design offers versatility for a wide variety of applications.

Principle of Operation

The 1301 Series regulators are direct-operated.Downstream pressure is registered internally through

the body to the underside of the diaphragm. When downstream pressure is at or above set pressure,

the disk is held against the orifice and there is no flow through the regulator. When demand increases,

downstream pressure decreases slightly allowing the regulator spring to extend, moving the yoke and

disk assembly down and away from the orifice. This allows flow through the body to the downstream system.

As the downstream pressure reaches its setpoint, it starts to overcome the spring force, which is sensed by the

diaphragm, moving the yoke and disk assembly up near its orifice, restricting flow across the regulator.

Overpressure Protection

The 1301 Series regulators have an outlet pressure rating lower than their inlet pressure rating. If actual inlet

pressure can exceed the outlet pressure rating,outlet overpressure protection is necessary. However,overpressuring

any portion of the regulators beyond

the limits in Specifications section may cause leakage,damage to regulator parts, or personal injury due to bursting of

pressure-containing parts.

Some type of external overpressure protection should be provided if inlet pressure will be high enough to damage

downstream equipment. Common methods of external overpressure protection include relief valves, monitoring regulators,

shutoff devices, and series regulation.

If the regulator is exposed to an overpressure condition, it should be inspected for any damage that may have occurred.

Regulator operation below these limits does not preclude the possibility of damage from external sources or from debris in the pipeline.

Startup

With installation completed and downstream equipment adjusted, slowly open the upstream and downstream block valves

while using pressure gauges to monitor pressure.

If adjustment is necessary, loosen the locknut (key 18, Figures 3 and 4), and turn the adjusting screw (key 15, Figures 3

and 4) clockwise to increase the set pressure or counterclockwise to decrease the set pressure. Monitor pressure with

gauges during adjustment. When adjustment is complete, tighten the locknut. If the desired outlet

pressure is not within the range of the regulator spring, install a spring with a desired range

according to the Maintenance section.
